Abstract: A large number of potential alphanumeric patterns are ordered in a predetermined sequence which is then used to construct a transition graph composed of machine states along one coordinate and alphanumeric symbols along the other. The intersections on that graph establish either the next machine state on the graph or the action the system should provide. Pattern recognition is thus possible against strings of alphanumeric characters received there-after by responding to the characters to determine a path of state transitions through the graph until an appropriate action indicator is reached. Ma­chines including the invention are dynamically configur­able and permit a variety of system management options to the user. The invention has particular utility for flexible configuring of the dialing plan and internal management of PBX type of telephone switching devices regardless of the pattern discipline associated with its external connections.

Abstract: Apparatus and method for producing coherent blue-green-­light radiation having a wavelength of essentially 490-500 nm. A diode laser (10), such as a strained-layer InGaAs/GaAs diode laser, provides a 980-1,000 nm beam (12), and a nonlinear crystal (19) of KTP (KTiOPO₄) produces coherent radiation (22) by noncritically phase-matched second-harmonic generation (SHG) of said beam. The beam preferably has a wavelength of essentially 994 nm for generating radiation having a wave­length of essentially 497 nm. The crystal is disposed within an optical resonator (18) and the frequency of the laser is locked to that of the resonator. Alternatively, two diode lasers (10,11) are oriented to provide orthogonally polarized beams each with a wavelength of 980-1,000 nm but within essentially 1 nm of each other, and the KTP crystal is orient­ed with its a and c axes parallel to the orthogonally polar­ized beams. The KTP crystal may have an associated optical waveguide along which the beam is propagated to enhance SHG efficiency.

Abstract: After a base region and a base contact region, a diffused resistance region and a pair of contact regions formed at each end of the diffused resistance region are formed, an silicon oxide film of essentially uniform thickness is formed anew on the surface of an epitaxial layer. In the silicone oxide film, a collector contact/doping window, a base contact window, an emitter contact/doping window, a lower layer electrode contact window, and a diffused resistance element contact window are formed simultaneously, then the base contact region and the diffused resistance element contact regions are shielded by a mask and a collector contact region, an emitter contact region, and a lower layer electrode contact region are doped. The method of manufacturing a semiconductor integrated circuit of the present invention has the advantages that all insulating films have a uniform film thickness, eliminates the problems of side etching when the contact windows or dopant windows are formed or of etching the element regions. It is possible to form element regions of the design size and a large margin of spacing for the isolating regions and the base region is unnecessary. A high degree of integration can be achieved.

Abstract: There is disclosed a method for managing an LRU (least recently used) cache in a staged storage system storing data sets on a prioritized basis. The method uses the signed difference between an assigned and actual hit ratio to dynamic­ally allocate cache size to a class of data and its correla­tion with the priority of that class. Advantageously, the hit ratio performance of a class of data cannot be degraded beyond a predetermined level by a class of data having lower priori­ty (assigned importance).

Abstract: Two strip patterns are successively projected onto the object to be measured, e.g. in time-division multiplex mode, by at least two projectors arranged at an angle with respect to one another, the period of the gratings in the projectors being the same. The strip patterns are recorded by a camera (1), and the strip phase ( phi 1,  phi 2) of the two projections is determined for each pixel in an image processing computer connected downstream of the camera. The differences ( DELTA  phi ) of the strip phase of the two projections are then calculated for the pixels in the computer. These differences are also fixed relative to the camera for movement of the projectors, and are summed in an image memory (9) over a multiplicity of video images.

Abstract: A high-frequency surgical apparatus for thermally coagulating biological tissues is described, in which a current monitor (25) is provided to monitor amplitude fluctuations of the HF current during each coagulation process, which current monitor generates, by means of a current/voltage transformer, an electric voltage proportional to the amplitude fluctuations of the HF current, from which, by means of a first detector, a first DC voltage proportional to the amplitude fluctuations is generated, and by means of a second detector, which acts as a peak value detector, a second DC voltage is generated, which rises proportionally with the amplitude of the HF current. The first DC voltage (Ua) and the second DC voltage (kUb), which is subdivided by an adjustable factor by means of a voltage divider, are fed to a voltage comparator, whose output signal sets a flip flop, as soon as the first DC voltage (Ua) becomes less than the subdivided second DC voltage (kUb). The flip flop output signal switches off the HF current until the latter is switched on again by the actuation of a manual switching device and/or by an automatic switching device. Instead of or in addition to this current monitor (25), an arc monitor (26) may be connected to the output of the surgical apparatus to monitor the occurrence of non-harmonic frequencies of the fundamental frequency of the frequency generator, which output contains a filter, which allows through at least one of the non-harmonic frequencies of the fundamental frequency of the HF generator produced by the electric arc. The output signal of the filter is fed to a voltage comparator, whose output signal resets a flip flop in such a way that the output signal of the latter switches off the HF current. <IMAGE>

Abstract: Image data of an original read by an image reader is analyzed by analyzer means (12) to be supplied to a neural network (14). An operator inputs scene information and desired finish information to the neural network with data input means (13). 
     The neural network calculates setup parameter values in compliance with a conversion rule specified by predetermined weighting values and functional forms, and sets these values in an image data converter. 
     Then, the operator corrects the setup parameter values on the basis of finish condition of the produced color separation films. The corrected setup parameter values are inputted to learning means (15). The learning means computes proper weighting values with which the neural network calculates setup parameter values equal to or approximate to the corrected setup parameter values. Such proper weighting values are supplied to the neural network as new weighting values.

Abstract: A capacitor (156) connected directly across the terminals of the primary inductance (32) of a transformer of a switched mode power supply and a separately wound inductor (54) connected between the primary inductance and the switching power transistor (42) form a lossless snubber circuit. The snubber circuit is more efficient since resistors are not used to dissipate the energy as unwanted heat. The capacitor (156) increases the transistor turn off voltage rise time, thereby reducing radiated emissions. The inductor (54) reduces emissions appreciably by absorbing the ringing that would otherwise occur after the transistor is turned fully off and increases the transistor turn on time to allow reduced emissions.
